(This latest release is a bug fix for version 2.3. It does not add any new features. If you are running 2.3, I'd recommend upgrading as the bug fixes should increase performance by up to 30%.)
Version 2.3 adds a new feature which allows you to exclude URLs from being woken. If you want to exclude a single site, use the option spwakeup.exe -exclude:http://server.mycompany.com/site.
If you need to exclude several sites, list them in file called exclude.conf located in the same folder as spwakeup.exe. Once listed on the exclude list, spwakeup will ignore that site, and any of its subsites.
Discovery mode is now turned on by default. If you want to disable discovery mode, use the runtime option
spwakeup.exe -nodiscover.
If you encounter trouble running against localhost, try specifying the site using the option
spwakeup.exe -site:http://server.mycompany.com, or use discovery mode.
If you need to wake up more than one Site, list them in a file called sites.conf located in the same folder as spwakeup.exe.
For complete instructions, run spwakeup.exe -help
